Frequently Asked Questions

What is the connector impedance?

The sum of the resistance to inductance and capacitance is what constitutes the connector's impedance. Notice that both 75 and 50 ohms connectors are similar; what changes is the inner dielectric, being the white part of the 50 ohm connector and the air in the 75 ohm connector. This dielectric gap causes them to have different capacitance, which causes the difference in impedance between them .

What is the impedance of a wire?

Impedance – Cabinet Wiring. The impedance of a speaker is basically a measurement of how hard the amplifier will have to work to drive that speaker. The impedance is measured in Ohms and is marked on the back of most speakers.

What is the impedance of a RG-59 video cable?

RG-59/U is a specific type of coaxial cable, often used for low-power video and RF signal connections. The cable has a characteristic impedance of 75 ohms, and a capacitance of around 20pF/ft (60pF/m). The 75 ohm impedance matches a dipole antenna in free space.

What is speaker wire impedance?

Explanation. Speaker wire is a passive electrical component described by its electrical impedance, Z. The impedance can be broken up into three properties which determine its performance: the real part of the impedance, or the resistance, and the two imaginary components of the impedance: capacitance and inductance.
